How do I load a new material from Cura into a UM3?

[threepoint 0]

After a lot of searching through Cura settings, UM support pages, and community forums, I am embarrassed to say that I'm not sure how to get my new material from Cura over to my Ultimaker 3 so that it's added to the list of recognized material types for loading new spools.

 

Isn't Cura supposed to send new materials over to the printer somehow? This didn't happen at the time I created the new material in the Preferences -> Materials tab, and it didn't happen when I sent the print job over to the printer, either. How do I force the materials to sync?

 

I want to use my spool of MatterHackers HIPS 2.85mm as a support filament for Extruder 2. (Extruder 1 contains MatterHackers PETG 1.75mm through a Mosaic 1.75mm->2.85mm adapter.) Here is what I did:

 

1. Set my active extruder to Extruder 1 in order to be able to see 1.75mm diameter filaments in Cura Preferences -> Materials.
2. Duplicated the "Generic HIPS" material in Cura 4.7 beta. 
3. Changed its diameter to 2.85mm and updated its name and several other settings. In order to be able to view the material again after changing its diameter, I had to switch the active extruder to Extruder 2. 
4. Changed the active extruder back to Extruder 1.
5. Started the print.
6. Saw the message on the printer about needing to load materials "HIPS".
7. Placed the spool onto the printer, pressed Select Manually, scrolled through the list of available materials, and did not see HIPS.

 

What am I doing wrong here? What's the right way to get new materials over to the printer?

 

Thanks!

The material is still linked to its origin material and therefore has the same UUID. You need to unlink it so it gets its own UUID. Only then it is uploaded to the printer.

...and the generic "HIPS" material is explicitly excluded in the UM3 definition (for whatever reason).

Maybe this plays a role in this case?

 

https://github.com/Ultimaker/Cura/blob/master/resources/definitions/ultimaker3.def.json#L16

 

BTW: It's perhaps worth to get to the bottom of this exclusion setting - is HIPS abrasive or such?

Better safe than sorry...

I've power cycled my UM3, unlinked the MatterHackers HIPS material from Generic HIPS, and sent the job to print again. I still don't see HIPS anywhere on the UM3's "Material Type" selector when trying to load Material 2. Is there something else I have to do to sync Cura with the printer?

[Dim3nsioneer 557]

The sync should happen automatically. Does it sync a newly downloaded material from the marketplace? When you test it, make sure the material is compatible with the UM3.

I just tried downloading and installing two materials from the marketplace (MatterHackers NylonX and Proto-Pasta Copper). I changed my Extruder 2 material to each of those and sent the job to print. After the printer complained that a material change was needed, I went to Materials > Material 2 > Select Type. Neither of those new materials were listed.

 

When is the sync supposed to occur? After I choose "Print over network" in Cura?

Depending on what print core you have mounted they might appear greyed out with a red exclamation mark symbol as they need the CC 0.6 printcore.

Cura should send them automatically if you are connected to the printer through Digital Factory (network or cloud). And it will show you a small dialog at the bottom center (see attached picture). That happens after Cura startup.

If it does not happen, something is broken in your Cura installation. The only way to get it running is afaik to "nuke" Cura, i.e. to clear all profiles and let Cura create a new installation. You can achieve this by deleting all content of the parent Cura configuration folder (menu help->show configuration folder and then two folders up "cura"); the better way than deleting is to rename "cura" into something like "cura.old" so Cura doesn't find it anymore but you would still have an easy way to go back.

I didn't get this warning with any of the three materials I've tried. I currently have an AA 0.4 core installed, which should be fine for HIPS.

I wasn't previously connected to Digital Factory or Cura cloud because I didn't see any need for it (and I don't like cloud solutions in general, and I am baffled at the thought of needing a cloud service just in order to use a new material). But I wanted to test this, so just now I enrolled my Ultimaker account and my printer, confirmed that my account was synced in Cura and my printer was in added to Digital Factory, power cycled the printer, and tried to select material again. No change.

I did this yesterday and it didn't help.

 

I'm starting to suspect that I'm hitting a bug now, rather than it being user error. Anything I should look for in cura.log? Are there debug flags I can enable somewhere?

Looking through cura.log I see these lines:

 

WARNING - [MainThread] UM.VersionUpgradeManager._getUpgradeTasks [328]: Failed to get file version: ../Protopasta_CopperAlloys_2019/S3_Metal fill HTPLA/Protopasta_CopperBrassBronze_HTPLA.xml.fdm_material, skip it

WARNING - [MainThread] UM.VersionUpgradeManager._getUpgradeTasks [332]: Failed to get file version: ../MatterHackers_NylonX/MatterHackers_NylonX.xml.fdm_material, skip it

I reset both Cura 4.6 and Cura 4.7 beta and found the same errors in their respective log files.

[Dim3nsioneer 557]

That might be an explanation why you don't see them. However, this is where e.g. @nallath might want to step in.

Looking at the marketplace profiles, both of these materials are not compatible with the Ultimaker 3. They do list the UltimakerS3 though. @threepoint, your profile says you have an Ultimaker 3. Is that correct?

Upon connection (so basicly; if you reboot cura, the sync has happend). You don't need cloud connection to sync materials.

Anyhow, please provide the full logs from Cura. The entries that you singled out are not the ones that are causing the problem.

 

Furthermore, you can check what materials are installed by checking http://{YOUR PRINTER IP}/api/v1/materials in the browser.

Thanks, @nallath. I've attached a copy of the materials from the printer API and the log from after the point of resetting Cura 4.6.2 and installing NylonX and Proto-Pasta (but not HIPS yet) from the marketplace. I noticed that the materials dump doesn't contain these. Are you able to find any hints on what went wrong?

Correct, I have the UM3, not S3. But I should be able to use any third-party material I choose.

[nallath 1,117]

As far as I can see from your logs, Cura attempted to send the materials to the printer. It also didn't seem to have received them, which usually happens because the printer refused them.

 

The main situation when this happens is when you duplicate a material and then forget to unlink the material. At that point it has the same GUID, which makes the printer think that it already has that material.

Anyhow, someone from the FW team will need to have a look at this, since this is as far as my knowhow on how the printer handles it goes. You could have a look at http://{PRINTER_IP}/api/v1/system/log right after you start up cura and have a look what pops up there.

@nallath I've extracted the logs from the printer via USB (easier than catching the logs over the web API) and found these lines:

I want to try deleting my custom materials from the printer in an attempt to force a resync, so I enabled developer mode and ssh'ed in, but I'm having trouble finding where the custom materials are stored. I browsed around and all I could find was:

@nallath I've deleted the MatterHackers HIPS material files from /var/lib/griffin/fdm_materials (but I've left other HIPS materials there), rebooted the printer, reopened Cura, and saw the message in Cura about sending new materials to the printer. I confirmed that the MatterHackers HIPS material showed up in /var/lib/griffin/fdm_materials with a new UUID. I re-selected the material for my model in Cura and sent the job to print. The printer said to load HIPS material into Extruder 2. I went to change the material type of Extruder 2 and HIPS is still not listed in the menu.

Thanks for reaching out to the firmware team. Can you tell me their usernames so I can @ ping them here? I am blocked on this and would love to help root-cause and resolve this. Thanks!

 

(Also, for my own debugging: Would you mind sharing the command to view and/or save log files via the shell? It looks like only the /tmp/flow*.log file is present on disk, and that one tends to be empty, so I suspect that the real logs are pulled from the database on demand when the user chooses to dump to USB. Can you give me a shortcut to just do that over CLI? Thanks!)

@nallath I've been monitoring the logs during my reattempts and I don't see anything new or obviously suspicious. I'm currently out of ideas for what to try next to get my material recognized. Would you mind checking with the FW folks to see if they can suggest an experiment? If nothing else, is there a command I can invoke to perform a forced full resync of materials / printer configuration? I suspect I might need to debug the griffin materials service, but I don't know enough python to do it confidently on my own.

What about the API? I don't have it in front of me right now, but there should be a link on the printer's "homepage".
The API provides functions to manage materials on the printer (if i remember correctly).

Hi @nallath and all,

 

I just wanted to bump this thread. I'm now on Cura 4.10 and the new firmware 5.2.17 and this is still an issue: I am trying to load HIPS material and it never shows up on the material selector page on the Ultimaker. I'd love to help continue debugging this with your guidance. Thanks!

[CarloK 201]

@threepoint I'm one of the firmware guys. A year ago I wasn't working on the UM3 so this problem never came to my attention.

 

I understand you want to add a new HIPS material and this doesn't show up in the material selection list. That's weird, from a quick glance, your material definition looks correct (only materials with color 'generic' are shown and the UM3 printer should be enabled for the material).

 

Just after the 5.2.17 release I discovered a problem: when we have multiple materials with the same name, then only 1 is shown. Perhaps this is what happens in your printer? You already have the Generic HIPS present.

 

I'm on holiday now so have no access to a printer. I can test again next week.

Thanks for looping in on this, @CarloK. I'm not sure that this is the same bug. Regardless of whether I have one or more than one HIPS materials defined in Cura, my UM3 has never given me the option during material loading to select "HIPS".

 

Re-reading the thread, @tinkergnome's post really sticks out to me:

...and the generic "HIPS" material is explicitly excluded in the UM3 definition (for whatever reason). Maybe this plays a role in this case?

 

https://github.com/Ultimaker/Cura/blob/master/resources/definitions/ultimaker3.def.json#L16

 

BTW: It's perhaps worth to get to the bottom of this exclusion setting - is HIPS abrasive or such? Better safe than sorry...

 

 

Could this be the reason that HIPS is always absent from the filament loading screen?

Edited August 13, 2021 by threepoint

Updated to Cura 4.11 and UM3 firmware 5.3.0.

 

No change to behavior: HIPS material is still (seemingly intentionally) blocked from being natively recognized by the printer despite showing up in Cura. I'm having to work around this by pretending that my HIPS material is ABS and manually forcing the printer to use it anyway each time I send a job to print.

 

I don't know why this is the behavior and why it appears to be unique to HIPS, but I'm starting to wonder if there was a policy decision made by the Ultimaker team to specifically discourage HIPS usage. If that is the case, I don't understand why. HIPS prints very well for me and is an excellent support material.

 

I would be really grateful for anyone on Team Ultimaker (especially anyone working on firmware) to weigh in and offer some guidance. Thank you!

[CarloK 201]

I checked the Generic HIPS material and it has no printers attached, which explains the material not being selectable in the printer. In fact, in Cura 4.10 the HIPS material is not visible either in the material selection list. HIPS is not supported (yet) by Ultimaker.

Perhaps the Generic HIPS material was visible in Cura 4.7, when you started this thread, and settings have been preserved during Cura updates.

 

When you duplicate a material, it also copies the list of supported printers. Since the Generic HIPS didn't support any printers, the material based off this won't support any printers either.

 

Cura is a poor tool for creating a new material, there are more settings than what Cura allows to configure. Our material suppliers get a separate tool for creating print profiles (lots of work).

 

In order to create your own Generic HIPS material you could duplicate a material that has more-or-less similar material properties, this will then copy the hidden parameters as well. When you name the material with brand 'Generic' it will reduce the number of material conflict warnings when starting a print.

Note:
Since you already experimented a lot with similar named materials you might run in another issue. The printer tries to reduce the size of the list of selectable materials and will only show 1 item for each available material type. So, when you have multiple HIPS materials, it will show only one. Which of the duplicate materials will show is kind of random (always the same on your printer, but might be different on another printer).

 

Remove all your HIPS materials from Cura, create a new HIPS as described above. Remove all installed materials from the printer (factory reset, or login to the printer and manually remove the files). Start Cura and connect to your printer. You should see a Cura message that it sends new materials to your printer.

I just created a Generic HIPS material based on PLA (Select 'Create material' in Cura) and another HIPS2 based on CPE+ (using 'duplicate', don't forget to select 'unlink'), and both are visible in my UM3.
